Smile!

Smile Helmet Via Boing Boing: the smile helmet:

A helmet for people in jobs which demand an unusual amount of smiling, such as air-stewards, receptionists and politicians. A sensor in the front of the helmet detects anybody within a 2 metre range, at which point the mouth is pulled into a broad grin by a small servo motor and some concealed fishing wire. The helmet addresses the facades of social interaction and explores our responses to affected expressions.

There’s video of the helmet in action.

Hey, it made me smile.
